* [misc] add contentId into the URL for protecting PDF stream contents
* [misc] gracefully handle missing ranges in serviceWorker
* [misc] support PDF stream caching for anonymous users
* [misc] polish header names and add URL to error message when fetch fails
* [misc] polish event handler registration
* [misc] limit serviceWorker scope to /project/ -- trailing slash
This will block the service worker from intercepting requests on the
project dashboard.
* [misc] add per-request feature flag for enabling PDF stream caching
* [misc] expose compile stats and timings to the frontend
* [misc] serviceWorker: support clsiServerId and compileGroup url params
* [misc] serviceWorker: polish header maps
* [misc] serviceWorker: drop TODO for p-limit -- the browser has a queue
* [misc] serviceWorker: drop verbose log message on every fetch
* [misc] cut down size of diff in backend code
* [misc] add test case for forwarding of pdf caching and metrics details
* [misc] serviceWorker: drop all the log lines
* [misc] serviceWorker: add boundary guards to the compile request regex

Retain a small part (6 or 9 bytes) of each chunk in memory for providing
the next iteration with enough context for finding the start/end marker
of a range.
